Abstract: Water resource carrying capacity and ecology deficit in the Shule river basin were studied using ecological footprints. The capacity gradually increased from 1 696.35 ha to 1 925.26 ha, the total ecological footprint from 19 714.23 ha to 32 236.35 ha, and ecological deficit from 18 017.88 ha to 30 311.08 ha from 2003 to 2007. The water resource ecological carrying capacity is presently overloaded in the Shule river basin. Because of increasing population growth and farmland expansion, there are more pressures on the regional water resources. In the future, measures such as taking an appropriate immigration policy, increasing public awareness of water conservation education, adjusting the industrial structure, and controlling the planting area should be carried out.
